METAL EASE-JOINT.

Specification of Letters Patent.

Application tiled December 15, 1915. Serial No. 66,9842.

To oit 'zz/item it may concern:

ile it known that il, HENRY N. BENTON, a

citizen or" the United States, residing at hiladelphia, in the county ot' Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements m Meto. Saslrdoints, of which the following is "iedficatioin if invention relates to improiements in i 'sash joints, the object of the invention to provide a joint in which improved corstruotions of munnions are rigidly secured together 'af'ithout the use of any third or means. "rtlaer object is to provide a securely int which two munnions at right angles to each other, one constituting a T- her and the other a cross shaped bar, are

'ly connected.

i .h these and other objects in view, the invention consists in certain novel features construction and combinations and arrangements parts as will be more fully hereinafter' described and pointed out in the 2:5 claires.

ln the accompanying drav-:ings: Figure 1 is a View in cross section through one of the munnions illustrating my improved joint. Fig. is a View in side elevation of munnion 3 is a plan view of the joint. Fig. la View in side elevation of munnion 2. Fig. 5 is a plan View of munnion l in position to receive the other munnion. F ig. G is a a'icw in cross section on the line 0 6 ot l 2. 7 is a View in cross section on the line ile-7 ot' fi, and Fig. 8 is a View similar to l illustrating a modification.

dy improved joint is composed of munnions l and 2. located at right angles to each other. lviunnion l is of general cross shape in cross section. .ln other words. the munnion l comprises a relatively thin web 5 pro- 'rided at opposite sides with laterally projecting flanges 3. rihese flange 3 extend o5 throughout the length of the niunnion, are spaced from both edges of the munnion, but are preferably nearer `one edge than the other as shown clearly in the drawings. Munnion 2 oi general 'lshape in cross o section. .in other words. munnion 2 comprises a relatively thin web (i provided at one edge with oppositely projecting flanges l which extend throughout thc length oi' the munnion. Munnion 2 is provided in the edge of its web G with a recess 7 of approxi mately the same width as the thickness of the web 5 of munnion l. Munnion l is provided with a Vfit-shaped opening 8 corre spending in shape to the shape ot' munnion 2 in cross section except that the opening 8 5@ is otl a length approximately the same as the width ot munnion 2 from the inner end of the recess 7 to the flanged edge of the munnion,

The wide portion of the opening 8 is 65 formed by cutting out the flanges 3 of mur nion l and the long part of the opening 8 extends transversely of the web portion 5 of muimion l. Atongue 9 is cut from the web of munnion l adjacent the wide portion of the opening 8, so that one wall of the tongue 5) constitutes one wall of the opening 8. The tongue 9 is located entirely within the outline oi the munnion, and is ot' a length appreciably greaterthan the width ot' the open- 75 ing 8, so that .it can be bent laterally as shown in Fig. 5, and he out of the way when the munnion 2 is inserted into the opening. lvl/hen this tongue 9 is bent as shovn in Fig. 5, munnion 2 can be inserted in the so opening 8. When the munnion is so inserted, and the recess 7 alines with the end of slot 8, munnion 2Ican be moved laterally so that its recess 7 will straddle the web portion of munnion l between the end of slot 8, 25 and the edge of the web. W'hen in this pov sition, the edges of webs 5 and 6 of the two munnions will be in alinement as shown clearly in Fig. i, and the ilanges et oi"- munnion 2 will be located in the wide portion so of the slot 8 ot' munnion l. Tongue 9 is then bent back to its former position, so that it constitutes a part of the web ot munnion l. and securely holds munnion 2 in its joint relationship to munnion l. It will be noted that the munnion l is oigan appreeiably greater width than munnion 2, and that the munnion 1 from its flanges 3 to one edge thereof is ot' the same width as munnion 2, hence the munnions when joined, have their edges at one side of the joint located in alinement. instead ot' providing a single tongue 9 as shown in Fig. 2, munnion l may he cut so as to provide two tongues l() shown in the modification` Fig. 8, which would be bent similar to the tongue 9 to allow munnion 2 to be inserted.

rarious slight changes might be made in the general form and arrangement of parts described Without departing from my in- 1w vention, and. hence I do not limit myself to the precise details set forth, but consider iiiyselir at liberty to make such changes and alterations as fairly fall within" the spirit and scope of the appended claims.

Having tbn's described my invention, what l claim as new and desire to secure by Letters Patent is:

l. A sash joint comprising two one having a notch in one edge, having a said latter murinion, said tongue being produced 'by forming two slits lengthwise of said niunnion and another slit connecting said first slits, one long edge surface of said tongue entirelyiorining one end of said slot, said tongue being laterally bendable to provide space additional to said slot to permit the insertion of said rst munnion, said first munnion after its insertion being movable transversely to said second inunnion to permittlie portion `forming `said notch to straddle the portion of said second munnion adjacent the opposite end of said slot, said tongue being movable into its original position after the first munnion has been moved into said straddling position, substantially es described,I I

2. A sash g'oint comprisingtvvo rniiiinions, at angles to each other, one inuiinioii being of general cross-shape section, the other inunniunnions, the other nion being oi general lV-shape transverse section, the .cross shaped inunnion having a "l"- shape' opening therein into ywhich the T- shape section its, seid cross-shape section being slit to provide a laterally bendable tongue directly adjacent the outer surface of the headportion of the "l-shape munnion, the end surface of the web of the "iT-shape 4o inuniiion/having a recess Vinto which a porthe T-sliape munnion,

slot therein, a tongue formed in misser i tion of `the web of the cross-shape inunnioii extends to form a lock, said tongue when bent out laterally providing space in addi'- tion to said opening into which said T-sinipe inunnion may be slid and afterward moved transversely to forni said lock, said tongue when bent to its original position serving to abut said outer surface of the head of substantially as scribed.

3'. A sash joint comprising two ninnnions at angles to eachother, oiieinunnion being ol" general Aorossshape sectijomthe other ninnnion being of general "iT-shape transverse section, the cross shaped muiinion having a. sliape opening therein into which the T shape section beingA slit to' provide tvvooppositel disposedv laterally bend. ble tongues directly adjacent tlie 'outer surface of the head portion ofthe l'sliape munnion, the. end surface o-theaweb of the 'iF-shape inun'nion hav in a recess into which a portion of the we of thev cross-shape iniinnion extends to form a lock, said tongues when bent ont laterally providing space in additionV to said opening 'in'tovvhich said T-'sliape iniin nion may be slid and afterward moved transversely to form said lock,saidtongues when bent'to their original positions serving abut said outer surface of the head o the T-shape inuniiion, substantially as describedu ln testimony whereof l have signed my name to this specification in the presence of two subscribing Witnesses.l q
